An abyssal head is a very rare drop from Abyssal demons and their superior counterpart, which require 85 Slayer to kill. Players may also obtain an abyssal head by placing an unsired at the Font of Consumption; this has a 5/64 chance, and as an unsired is a 1/100 drop, this effectively makes it a 1/1280 drop.

If players wish to have the abyssal demon head mounted, it must be taken to the taxidermist in Canifis. She will charge 12,000 coins and take the abyssal demon head away, giving them a stuffed abyssal head. They can then mount it in their player-owned house using 2 mahogany planks.
